Comparing Multicomponent and Isometric Multicomponent Training: Impact on Fitness, Health, and Life Quality in Heart Patients

The goal of this clinical trial is to evaluate if a multicomponent training program (MCT), including aerobic and resistance exercises, or an isometric multicomponent training program (IMCT) can improve physiological, physical fitness, mental well-being, and quality of life in adults and elderly with a history of cardiovascular diseases (CVDs) currently stabilized. The main questions it aims to answer are: Does MCT or IMCT improve physiological parameters, physical fitness, mental well-being, and overall quality of life compared to a waitlist control group (WLCG)? Does IMCT provide superior physiological improvements compared to MCT? Researchers will compare: * MCT (a combination of aerobic, mobility, and resistance training exercises) * IMCT (a combination of aerobic, mobility, and isometric exercises) to see if these interventions improve health and quality of life outcomes compared to WLCG (participants not engaging in structured physical activity during the study), and if there will be significant physiological differences between MCT and IMCT . Participants will: * Complete assessments of anthropometric, hemodynamic, physical fitness, and psychological parameters at baseline (T0) and after 24 weeks (T1). * Be randomly assigned to one of three groups (MCT, IMCT, or WLCG). * Engage in a 24-week structured training program (MCT or IMCT) supervised by exercise professionals, including: * Warm-up sessions (10 minutes, low-intensity walking). * Main sessions (40 minutes): aerobic, mobility, resistance (MCT), or isometric (IMCT) exercises. * Cool-down sessions (10 minutes): breathing and stretching exercises. This study will provide insights into the efficacy of tailored physical activity interventions for individuals with a history of cardiovascular conditions.
